![]() ![]() Step 3: At time = 2, P1 arrives in the waiting queue and P4 continues executing. ![]() Step 2: At time = 1, process P3 arrives in the waiting queue but P4 continues executing as it only needs to complete 2 units. Step 1: At time = 0, P4 arrives and starts executing. ![]() Non-preemptive: The CPU is held by a process until the process reaches the waiting state or terminates.ĮXAMPLE: Consider the following five processes: Process Queue Types of Shortest Job First Algorithmsįollowing are the two types of SJF algorithms:ġ. Shortest Job First (SJF) reduces the average waiting time for other processes significantly. In case of Shortest Job First scheduling algorithm, the process with the smallest execution time gets executed next. We offer you a brighter future with FREE online courses Start Now!! ![]()
